For me it's pure nostalgia.
When I became aware of 10 speed derailleur equipped bikes as an 11 year old in 1963 I thought they were really exotic I was riding a 3 speed Schwinn Traveler at the time.
I picked up a brochure from the neighborhood Schwinn dealer and saw the 15 speed Sierra & Superior models. Now those were just hyper-exotic!
I kept my eyes open for one for decades but they were not to be found in my area.
With the advent of the internet I was finally able to find one.
Seems kind of stupid now, but when I joined this forum in 2003 I used the bike model name as my forum name.
I have many better bikes now, but I still cast my eyes fondly on this one. It takes me back to being 11-12 years old, when life was much simpler.
My 1963 Schwinn Sierra(not bone stock).
